Discover the full-day boat cruise from Kos to three islands, featuring scenic stops, dolphin sightings, a Greek lunch, and plenty of free time to explore.
If you’re visiting Kos and craving a taste of the surrounding islands, this full-day boat cruise offers a fantastic way to see three different spots without rushing. Priced at just over $35 per person, it’s a budget-friendly option that promises a mix of scenic views, local charm, and memorable moments, all wrapped in approximately 7 hours and 15 minutes of adventure.
What we love about this experience is how smoothly it balances sightseeing with relaxation. You get to explore quaint villages, swim in crystal-clear waters, and even spot dolphins, all while enjoying a delicious Greek lunch on board. However, one thing to consider is that the boat can get quite full — if you prefer quiet, early arrival and shaded seats might be your best bet. This tour suits travelers who want a fun, social day out with plenty of photo opportunities, local flavor, and a bit of the sea breeze.

This full-day cruise, operated by Odyssey Boat Cruise, has earned a glowing reputation with a perfect 5.0 score from over a thousand reviews. It’s praised for its excellent organization, friendly staff, and value for money. The tour is designed to maximize your time, combining scenic cruising with stops that give you a real taste of local life and natural beauty.
The tour kicks off at 10:00 am from the Port of Kos and runs for about 7 hours — a good span for those who want to see a lot without feeling overwhelmed. The group sizes are limited to 135 travelers, making the experience feel intimate enough for conversations but lively enough for social fun.
More ways to experience Kos from the water include these boat tours

Our first stop is the charming village of Vathi, situated in a striking natural fjord. The boat glides into this serene inlet, revealing lush green hills, caves, and the quiet streets of Vathi. It’s a perfect moment for photos — the scenery is as postcard-perfect as it gets. Reviewers often mention the peaceful vibe of Vathi and the opportunity to explore at leisure.
You’ll have about an hour here, giving you enough time to wander the stony streets, sample local sweets, and sip on the famous homemade orange juice. The sponge warehouses offer a glimpse into the island’s traditional livelihood, which is a fascinating bit of local history. Several visitors highlight that this stop is less touristy and more authentic, offering a genuine taste of island life.
As the boat heads toward Plati islet, it passes fish farms, which often attract dolphins. Many guests rave about the sightings — wild dolphins frequently jump out of the water, seemingly curious about the boat’s presence. One reviewer noted that “the smell of fish attracted dolphins, and we often saw them jumping,” adding an enchanting element to the cruise.
The highlight here is the swim stop at Plati, where the water’s clarity impresses everyone. The sand is soft and shallow enough to wade or snorkel, making it ideal for families or less confident swimmers. The water’s transparency is a big plus, with many visitors commenting on how easily they could see the sandy bottom through the vibrant blue.
While on board, there’s a happy hour — cocktails are served at reasonable prices, enhancing the relaxed summer vibe. The crew’s friendliness and attentiveness shine here, often receiving praise for their helpfulness and fun attitude.
The final stop is Pserimos, an unspoiled little island inhabited by just 15 families in winter, swelling during summer. The island feels untouched and quiet, perfect for those seeking a peaceful escape. You’ll have about an hour to explore, swim on the sandy beaches, or just kick back at a local taverna.
Reviewers frequently mention how Pserimos is a hidden gem, ideal for relaxing, with some appreciating the chance to walk along the shoreline or discover the island’s little paths. There are cafes and tavernas where you can grab a cold drink or a snack if you prefer to stay on land.

Your ticket includes a Greek BBQ lunch with options for pork, chicken, or vegetarian dishes. The meal is hearty, flavorful, and well-presented — a highlight for many, especially those who appreciate authentic local cuisine. Tzatziki, bread, and salads accompany the main dishes, ensuring everyone leaves satisfied.
Extras like alcoholic beverages, sodas, and bottled water can be purchased on board, giving you the flexibility to enhance your experience without feeling pressured to buy. The bar area is well-stocked and reasonably priced, based on reviews describing cocktails at around €3.50.

The tour departs from the Port of Kos at 10:00 am, so arriving early is advisable if you want a shaded spot or to secure a comfortable seat. The boat can get crowded, and some reviewers mention that seating, especially in the sun, can be tight — bringing sunscreen, a hat, or a foldable chair might enhance your comfort.
The tour is suitable for most travelers, including families, as long as you’re prepared for a full day at sea. Service animals are allowed, and the activity is accessible near public transportation. Be aware that if the weather turns poor, the tour may be canceled or rescheduled, with full refunds offered.

Many reviews highlight the knowledgeable crew and their effort to make the day memorable. One reviewer praised the captain’s quick response when dolphins were spotted, which really added a special touch to the trip. The local guides on land, like in Vathi and Pserimos, are often appreciated for their friendliness and insights into island life.
Several travelers mentioned the good value for money, noting that the included meals, scenic stops, and dolphin sightings made this a worthwhile experience. Some pointed out the lively atmosphere on board, with music and cocktails enhancing the relaxed vibe — perfect for social groups or families.
That said, a few travelers noted that the boat can be quite full, and comfort isn’t always perfect, especially in peak season. Some mentioned the loud music or the lack of shaded seats, so planning accordingly can make the trip even more enjoyable.

For anyone looking to combine island hopping with a fun, social day at sea, this cruise offers a balanced mix of sightseeing, swimming, and cultural flavor. The stops are genuinely charming — from the tranquil streets of Vathi to the untouched sands of Pserimos — and the chance to spot dolphins adds a pinch of magic.
The cost is very reasonable considering the inclusions: a tasty barbecue lunch, free time for exploration, and multiple scenic stops make this a great value. The friendly crew, knowledgeable guides, and positive reviews suggest you’re in capable hands.
This tour is especially suited to travelers who want a hassle-free way to see multiple islands, enjoy good food, and experience authentic Greek island life without the stress of organizing transport or figuring out schedules. It’s perfect if you’re after a relaxed, social day out with plenty of memorable moments.
